/* Hallmark · pre-emit critique: P4 H4 E4 S5 R3 V4 · weakest: R, many interactive parts; kept to one data model and hairline frames so they read as one instrument, not a toy box */
/* Hallmark · answered F4 · the success and error recipes are states of the one primary button, not extra buttons */
/* Hallmark · dismissed 49 · tabs and logo tiles pair a short title with a one-line subtitle inside one button, by design, and none of them wrap awkwardly at 320px */
/* Hallmark · dismissed 23 · bars and gauges are 6 to 22px parts inside frames, nowhere near viewport scale */
